How to Select Seismic-Resistant Cable Tray Supports
Engineers typically use seismic design codes and standards to determine the appropriate design parameters for cable trays based on the seismic hazard level of the site. However, one often overlooked aspect is the seismic resistance of cable trays. During an earthquake, cable trays are exposed not only to gravity loads and normal service loads, but also to lateral movement, vertical acceleration, vibration, and building drift. If these. Eaton's TOLCO seismic bracing solutions help protect people and non-structural components during an earthquake. Box 23205, Pleasant Hill, CA 94523, (510) 934-4212. There is no charge for reports requested by EPRI member utilities. Cable trays, being an integral part of building electrical and communication systems.
